Bright students, in particular, he said, could spend valuable time puzzling over errors in mathematical notation that a less astute student might overlook.
These accounts have shed light on some puzzling tactical errors but most reflect the time-honoured dictum that victory has a thousand fathers while defeat is an orphan - everyone involved with the campaign can point to some mistake someone else made, in order to exculpate him or herself.
Simulation studies of quartet puzzling revealed that errors made in the choice of the individual quartets were propagated throughout the puzzling process, which in some instances caused inaccurate tree reconstructions [ 18].
If there is an error, even a puzzling metaphysical one as to the actual existence of a specific bottle, it is invariably the retailer's boob, not the column's.
To be fair, the game was more given away by Djokovic than taken from him – the sun was in his eyes again, and there were three unforced errors – but it is rather puzzling.
Attempts to reduce these errors include variations on quartet puzzling which limit the quartets that are examined, provide different weights for individual quartets, or modify the puzzling procedure [ 18- 20].
This puzzling result could just represent type I error, but it is not the only case of a "flip-flop" phenomenon, whereby association with a risk allele is replicated, but in the opposite direction.
How the SAC detects the errors and controls the cell cycle is complex and still puzzling.
The final reason Greenspan's alleged error rate was maddening - or at least deeply puzzling - is that, as far as I or anyone could tell, it seemed to be plucked from thin air.
If there is no irony intended in this puzzling double-edged comment, and if Gilbert really agrees that memory and imagination are forms of error, I'd like to register my strong dissent.
